4 Introduction to Neoplasms of the Bladder and Urothelium 7 Urothelium The layer of transitional epithelium that lines the wall of the renal pelvis, ureters, the bladder, and parts of the urethra The urothelial lining may be exposed to urinary carcinogens derived from tobacco smoke, dietary, occupational or environmental chemicals while the lining is performing its usual function to collect, store, and transport urine Carcinogenic urine can sit in the bladder or collecting ducts for long periods of time constantly exposing the urothelial lining to carcinogens. 8 4

5 Field Effect Theory The field effect theory suggests that the urothelium has undergone a widespread change, perhaps in response to a carcinogen, making it more sensitive to malignant transformations. As a result, multiple tumors arise more easily. Recent scientific evidence supported by molecular analysis of microsatellite alterations and X-chromosome inactivation status in cells examining coexisting tumors leads to the development of multiple, genetically unrelated tumors further supporting the field effect theory. 9 Implantation Theory Implantation theory suggests that the multiple tumors are of monoclonal origin, arising from a single malignant transformed cell which proliferates and spreads throughout the urothelium either by intraluminal spread with secondary implantation at different sites within the urinary tract or by intraepithelial migration. The implantation theory suggests that tumor cells in one location lose their attachments and float in the urine until they attach (implant) on another site. Urothelial tumors may spread in a head-to-toe direction, for example from the renal pelvis to the ureter(s) to the bladder. 10 5

Clinical T1a and T1b Incidentally detected during a TURP for BPH no elevated PSA Clinical T1c and T2 PSA positive only T1c not clinically evident Note: Tumor found in one or both lobes by needle biopsy, but not palpable or visible by imaging, is classified as T1c DRE detects tumor T2 (palpable) clinically evident then you can determine if 1 or both lobes involved and level of involvement Clinical T3 DRE detects palpable disease sufficient to indicate the tumor has penetrated thru the prostate capsule including seminal vesicle 48 24

25 Clinical Stage Illustrations Material provided by Prostate Cancer Research Institute (PCRI) 49 Clinical Stage: Why Important? Clinical T4 Indicates local invasion of adjacent structures.
